Be it known that Lil/'umani Farmsen, a citizen of the United States, residing at Oakland, in the county of Alameda and State of Cali-corina, have invented a new and useful Motor-Pl W Tractorc My inve tion relates to imprevenients in motor ploy: tractors.

lt consists of a plurality of disk colters pivoted at ends of radially disposed spokes or arms nwnnted equidistant upon a niotor power driven revoluble shaft. Said shaft is journaled upon the rear ends of a pair ot rearwardly extending arms. The forward ends of said arms are pivotrlly attached by sleeve around the rear driving` axle of a self propelled motor truck. Means for raising and'lovvering said arms are provided. A trailing' gang of plovvs are hitched to rear end of said motor truck. Said plovvsare an adjunct to the disk colters, and the plovvs are mounted so that each plow point follows directly in the cuts made by the disk colters, one plovv for eacln disk cut Said moto;` power driven revolulole shaft having the disk eolters mounted thereon may be revolved by a sprocket clain deriving rotary motion from the d; Wheels of an ordinary motor A the constrnetio i of parte, as liereinaiter more fully described and elaiiiedf having; reference to accoinganying drawings in Winch-'- Figure is side elevation ef my device Fig. i an ,View of the same.,
